Hello NetPros,
I do hope you all keeping well and safe. I have a sceanario that I need you much valued not to mention esteemed input and opinion.
Background Information
Now for the last 4 months I have been working on a WAN (HQ + 5 Branches) solution for a CCTV system. The network has 2 models of switches namely
- WS-C2960X-24PS-L {15.4 W-per-port maximum, 370-W switch maximum}
- WS-C2960X-48FPD-L {30 W-per-port maximum, 740-W switch maximum}
The cameras are non-Cisco (Truvision) with the following power ratings:-
- Domes 5.5 Watts
- Bullets 14.5 Watts
- PTZ internal 9 Watts
- PTZ external 60 Watts
All the PTZs are independently whereas the Domes & Bullets are powered via PoE. The cameras are set to record on motion (recording is done when the camera senses motion).
Recording is done locally as each branch has its own server, the branches are connected to HQ via MPLS.
The Challenge/Problems
As we went to commissioning, the client complained of missing recordings. After careful analysis I made the following observations:-
- The cameras with issues (missing recording) were the bullet camera that have a 14.5W rating.
- Those cameras with issues (missing recordings) were connected to the WS-C2960X-24PS-L switches.
- All the affected WS-C2960X-24PS-L switches had a high number of cameras 15-18.
- Bullet cameras connected to WS-C2960X-24PS-L switches with few cameras have NO issue.
- Bullet cameras connected to WS-C2960X-48FPD-L switches with few cameras have NO issue.
Additional Information
- Configuration are standard on all switches (sample are attached)
- IOS image across the network is c2960x-universalk9-mz.152-7.E3.bin
As stated in the beginning, I kindly and humbly seek your valued opinion as to what could be wrong on the network end of things……
Regards & Respect
